Each suggestion's share of US babies has followed a curve close to Fiona's since 1880, and its recent number of babies is within about twelve times Fiona's, so the names are in the same league. Names starting with the same letter as Fiona or with the same ending are left out, so the names go together without matching. Spellings of Fiona itself are excluded.
